"Sharad Yadav should not talk about principles in politics. Socialist leaders never support dynastic politics, the corrupt, and corruption," Nitish Kumar told media persons here after his weekly 'Lok Samvad' programme.

Without naming Rashtriya Janata Dal chief Lalu Prasad and his family, who are facing corruption charges, Nitish Kumar said former Janata Dal-United President and former Union Minister Sharad Yadav's 'Sanjhi Virasat Bachao' event or 'save common heritage' was to support dynastic politics and corruption.

Sharad Yadav had organised the event at the Constitution Club in Delhi on August 17, which was attended by more than a dozen opposition parties.

The Bihar Chief Minister justified his decision to join hands with the Bharatiya Janata Party and form a new government in the state. "I took this decision to safeguard the interests of Bihar and for its development," he said.

Nitish Kumar, who is also JD-U President, said the Election Commission had already rejected twice the claim of Sharad Yadav's faction that they were the real JD-U. There will be no problem if they approach the commission again, Nitish Kumar said.

Earlier, Sharad Yadav called Nitish Kumar "selfish and betrayer" for breaking the Grand Alliance comprising the JD-U, the RJD and the Congress and forming a new government in Bihar with BJP help.

Nitish Kumar was silent on the political uproar over the unprecedented growth in BJP President Amit Shah's son's business as well as the economic slowdown in the country.
